  The present invention relates to a production process for a phenols novolac resin obtained by reacting phenols with formaldehydes, wherein they are reacted in the presence of a metal compound used as a catalyze for the reaction described above, and a chelating agent is further added in order to deactivate a catalytic action of the metal compound and a resin-coated sand prepared by using the above phenols novolac resin. It is possible to provide a process for producing a phenols novolac resin having an ortho rate of 30 to 60 %, suitably 40 to 55 % at a good yield (70% or more) and a resin-coated sand having a high curing property prepared by using the above phenols novolac resin.

  本发明涉及一种酚醛树脂的生产工艺，这种酚醛树脂是由苯酚与甲醛反应得到的，其中苯酚与甲醛是在作为上述反应催化剂的金属化合物存在下反应的，为了使金属化合物的催化作用失活，还进一步加入了螯合剂，以及使用上述酚醛树脂制备的树脂包覆砂。 通过使用上述酚醛树脂，可以提供一种生产酚醛树脂的工艺，其正交率为 30%至 60%，适当情况下为 40%至 55%，且收率高（70%或更高），还可以提供一种具有高固化性能的树脂包覆砂。
